those are all great laptops along with the aopen1557g
internally hardware wise they can be configured roughly the same... and when you have a system thats the same hardware wise it really does come down to the nitty and gritty in aesthetics, funtionality, layout, additional small features
(which isnt usally advertised on a sale page... thats where owner reviews from this forum come in handy

@ pctorque)
although ive only owned and seen the compalcl56 i can comment about what ive read from other owner reviews:
8050
-looks the best hands down
-gets 3.5 hours mobile time (lowest of the bunch)
-ctrl key is not where its normally suppose to be (fn key is in its place)
-left palm rest gets warm
-has widesceen display so viewing angles will be better than CL56
cl56
-prolly the ugly duckling of the bunch, aesthetically
-gets 4.5 hours which is inbeteen the asus and the 8050
-keyboard layout is perfect, does not have numberpad like on the 8790
-palm rests do not heat up, nor does the laptop anywhere except for bottom rear... excellent thermal designs on the inside
-standard sxga+ screen... while it may be fien for some.. some others who need a presentation type display feel that it is inadaquiet
asusm6n (9700)
-2nd best looking of the bunch
-gets the most mobile time (5 hours+) and has dual battery support (for 8 hrs)
-keyboard is also perfect on this, does not have numberpad like on 8790
-unsure about heat warming up anywhere,,, might want to ask holywarsxxx or mister569
-comes with widescreen which would prolly be bette than CL56 interms of better viewing angles
-gpu on the m6n only comes in 64mb... which is fine for games, but some more intensive ones like farcry may not run very well with all graphic detail turned on high,, u may need to make some comrpormises
